1. Cold Solder Joints Cold solder joints occur when the solder fails to melt completely or when there is insufficient heat transfer between the solder and the components. This results in a dull, grainy appearance and a weak mechanical and electrical connection. To avoid cold solder joints: – Ensure the soldering iron is at the […]
Why Are PCB Test Coupons Important? PCB test coupons play a crucial role in ensuring the quality and reliability of the final PCB product. By including test coupons in the manufacturing process, PCB fabricators can: Monitor Process Consistency: Test coupons help manufacturers ensure that their production processes remain consistent and within acceptable tolerances. This is […]
Introduction to Solder Mask and Its Importance Solder mask, also known as solder resist or solder stop mask, is a thin protective layer applied to the copper traces of a printed circuit board (PCB). Its primary purpose is to prevent solder from adhering to areas where it is not intended, thus preventing short circuits and […]
What is Electrostatic Powder Coating? Electrostatic powder coating is a popular method used for applying a protective and decorative finish to various metal surfaces. This process involves the use of a dry powder that is electrically charged and sprayed onto the surface of the metal object. The charged powder particles adhere to the grounded metal […]
What is a PCB Solder Mask? A PCB (Printed Circuit Board) solder mask is a thin layer of polymer that is applied to the copper traces of a PCB. The main purpose of the solder mask is to protect the copper traces from oxidation, prevent solder bridges from forming between closely spaced pads, and provide […]

RAYMING, a leading provider of PCB fabrication solutions, offers a wide range of audited PCB fabrication […]
Introduction to PCB Fabrication and Common Issues Printed Circuit Board (PCB) fabrication is a complex process that involves multiple steps and requires precise control over various factors. Multilayer PCBs, in particular, pose additional challenges due to their intricate structure and the need for precise alignment between layers. In this article, we will discuss seven common […]
Introduction to PCB Soldermask Printed Circuit Boards (PCBs) are essential components in modern electronics, forming the backbone of countless devices we use every day. One crucial aspect of PCB manufacturing is the application of soldermask, a protective layer that covers the copper traces on the board. While soldermask comes in various colors, green has emerged […]
What is LPI Soldermask? LPI (Liquid Photo Imageable) soldermask is a type of protective coating applied to printed circuit boards (PCBs) to protect the copper traces from oxidation, prevent solder bridges, and provide electrical insulation. It is a photosensitive polymer that is applied as a liquid and then cured using UV light. LPI soldermask is […]
What is PCB Soldermask and Why Remove It? Soldermask, also known as solder resist or solder stop mask, is a thin lacquer-like layer of polymer applied to the copper traces of a printed circuit board (PCB). Its primary purpose is to prevent solder from bridging between conductors and creating short circuits during the soldering process. […]
